Dinosaur Cloning

Cloning is the creation of an organism that is an accurate genetic replica of another. Ever since various dinosaur movies came in Hollywood many people have begun to wonder if the cloning of a species like dinosaur, from a prehistoric portion of DNA is possible. These ideas sound extremely sensible as biologists have succeeded to clone a sheep. But there are several important hurdles that will keep the idea of dinosaur theme parks far away from realism.

The main problem is finding a well preserved dinosaur DNA. Though such DNAs have not been found, scientists believe that there may be an egg preserved wholly in an implausibly huge piece of amber. Since it is hugely impossible that a cell carrying the complete dinosaur gene will be found, scientists have to put together many separate strands of DNA from diverse sources. This can be achieved only after knowing the comprehensive and exact cycle of any one of the dinosaur species.

Dinosaurs need a surrogate mother to be cloned and dinosaurs already being extinct, this is a difficulty. As birds are directly descended from dinosaurs few scientists have considered using ostriches and its eggs for this reason.

Scientists might eliminate the nuclear DNA from the egg of an ostrich before the egg's shell is formed and insert the dinosaur DNA. The egg's shell will get formed while the egg is still inside the bird and later might be laid and incubated by the ostrich. It is also possible to do the same with the egg of a crocodile. Dr. Mary Schweitzer is researching on organic substances found in dinosaur bones at the Museum of Rockies in Montana, but declines to confirm dinosaur DNA as she is still uncertain. The possibility of dinosaur cloning [http://www.dinosaur-information.com] could be assured only if dinosaurs weren't extinct.
